Which of the following is incorrect in a galvanic cell?

Options

  1. AOxidation occurs at anode.
  2. BReduction occurs at cathode.
  3. CThe electrode at which electrons are gained is called cathode.
  4. DThe electrode at which electrons are lost is called cathode.

Correct answer

D. The electrode at which electrons are lost is called cathode.

Step-by-step solution

The electrode at which electrons are lost is called cathode isincorrect, because electrode at which electrons are lost is called anode as oxidation, that is, oxidation takes place at anode.
